Current Cost Support Forum

hi, any chance of changing the CT sensors to one way flow, when using current this could show the live usage and show a red LED on the energy monitor, when current flows the other way this would not be recorded so would register as 0 and show up as a green LED . . . so from a quick glance across the room if its red i know i am importing and green i am exporting

or if any one knows how to do this then post a comment

No! Of course you _can_ get monitors that detect the direction of current flow, but the cc clamps are a relatively low cost, safe & non intrusive. They detect the magnitude of the current and can't tell its direction.

It is possible to use connect 2 clamps and 2 transmitters and a monitor and then use software to subtract the house power from the solar to get the 'direction' but this needs a bit of computing power. To see how do that I'm afraid you'll have to do what you should've done before posting & read the extensive discussion about this on this forum! ie rtff...

Why dont Current Cost make a device that can accurately calculate Household electrical consumption, subtracting

the generated exported solar power from the actual imported electricity?

Many people would buy it.

I'm going out on a limb here, so i may be wrong but.....

As far as i'm aware, current clamps (not neccesarily current cost clamps) would normally give out a positive or negative voltage depending on the direction of any current flow.

Therefore, using two clamps connected together in series, in opposite polarity you would get a differential reading. One clamp would subtract the value of the other, so to speak. You would of course, only be showing a difference between on grid and off grid, not the total houshold consumption.

I don't know if this is of any use to anyone or if it would work but maybe someone can do something with the idea?
